Rail vehicle comprising a trough-shaped inner floor

ABSTRACT

A rail vehicle for passenger transport. The rail vehicle has at least one carriage with a trough-shaped inner floor section.

The invention relates to a carriage for a rail vehicle.

Carriages in most cases have a wooden floor and, conventionally, also in the buffet carriage or in the galley carriage. At this location, but not only there, leakages, for example, of water-carrying fitted modules, such as, for example, a washing module, can lead to water being introduced into the carcass of the carriage, which may lead to corrosion.

An object of the invention is therefore to prevent the introduction of leakage water into the carcass.

The object is achieved with the subject matter of the independent patent claim 1. Developments and embodiments of the invention are set out in the features of the dependent patent claims.

A rail vehicle according to the invention for passenger transport comprises at least one carriage, which has an inner floor which is constructed in a trough-like manner. The inner floor is suitable as a floor for persons or for the construction of fitted modules. It delimits in particular an inner space of the carriage, in particular a passenger space, with respect to a carcass of the carriage, so that leakages within the inner space cannot flow into the carcass which is located below. The term carriage refers in this instance to all rail vehicles for conveying persons and is not intended to be limited to driveless carriages, but rather driven vehicles are also included. Goods vehicles, for example, for bulk goods are, however, excluded. The carriage is in particular a so-called galley carriage.

Water-carrying fitted modules are then intended to be referred to accordingly as water-carrying galley modules. The term galley is intended in particular to be understood to refer to the kitchen of the rail vehicle. The floor of the galley has the inner floor which is constructed in a trough-like manner. In particular, it delimits the galley with respect to an additional passenger space.

According to a development of the carriage according to the invention, the trough-like inner floor is water-tight or coated in a water-tight manner, for example, the inner floor comprises wood, which is provided with an impregnating layer. The term water-tight is intended to be understood to refer in general to containers when no visible external discharge, no residual or increasing occurrences of penetration of moisture and no measurable decrease in the water level can be determined within an examination time of 48 hours.

Another development of the solution according to the invention can be seen in that the trough-like inner floor has a circumferential profile at the edges of an otherwise substantially planar surface. The profile which extends around the edges forms the trough walls of the trough-like inner floor. The planar surface accordingly forms the trough base. The circumferential profile is in this instance, as explained, placed on the otherwise substantially planar surface and securely connected thereto, in particular connected in a materially engaging manner, for example, adhesively bonded or screwed and adhesively bonded. Gaps which may occur between the profile and surface may be joined with a water-tight joining compound. Both the surfaces of the circumferential profile directed into the inner space of the carriage and the otherwise substantially planar surface are water-tight or coated in a water-tight manner.

The circumferential profile comprises in a further development an angular strip having at least two members, whose members in particular form an angle between 60° and 120°, in particular between 80° and 100°, in particular of approximately 90°.

The profile is in particular constructed as an angular strip which has two members at right angles. The angular strip is in particular produced from a water-tight material, for example, from a metal or a metal alloy, in particular from a stainless steel or high-grade steel, whereby it is water-tight. However, it can certainly also be produced from a polymer material. The angular strip is, for example, arranged in such a manner that a first member is arranged horizontally and consequently parallel with the otherwise substantially planar trough-like inner floor portion and a second member extends vertically, for example, at least 5 mm, in particular 10 mm and more, for example, 15 mm, over the otherwise substantially planar trough-like inner floor portion. If the angular strip has a right angle between the members thereof, the second member stands in a perpendicular manner on the otherwise substantially planar trough-like inner floor portion. The angular strip could also be constructed in a T-shaped manner and consequently have three members.

For example, the first member is arranged below a water-tight anti-slip layer, in particular between a water-tight anti-slip layer and a floor plate which is located therebelow.

According to a development, the angular strip is adhesively bonded to the otherwise substantially planar inner floor portion, in particular the first member of the angular strip is adhesively bonded to the otherwise substantially planar inner floor portion. The second member of the angular strip may be covered by means of another structural element, for example, a foot plate or a wall.

In a development, the rail vehicle has, in a transition region between the trough-like inner floor portion as a first floor portion and another substantially planar floor portion, a foot plate for connecting these two floor portions. The foot plate forms a portion of the profile which extends around the edges of the trough-like inner floor portion. It is sealed with respect to the floor portions, in particular by means of water-tight joining compound which is introduced. According to an embodiment, it has a height with respect to the floor portions of at least 10 mm, for example, even 15 mm. The floor portions comprise, for example, plates which are coated in a water-tight manner. A development of the foot plates involves it being constructed in such a manner, in particular having an undercut, that it vertically overlaps the floor portions. Between the foot plate, in particular between the overlapping region of the foot plate, and the floor portions, water-tight joining compound is introduced.

In another development of the invention, there is provision for the carriage to comprise collection troughs, in particular of high-grade steel, which are arranged on the inner floor below water-carrying fitted modules. Water-carrying fitted modules are, for example, washing machines or wash basins which are placed on collection troughs between them and the trough-like inner floor. Leakage water of the water-carrying fitted modules is thus already received in the collection troughs.

According to another development, the collection troughs are produced from a deep-drawn high-grade steel.

In a further development, the collection troughs extend as far as a location behind the water-carrying fitted modules between the fitted modules and the walls of the carriage. They have a base and walls which surround the base, which walls behind the fitted modules in particular have a vertical height with respect to the base of at least 600 mm. According to an embodiment, the walls extend behind water-carrying fitted modules up to the height of the water-carrying fitted module. A transfer of leakage water into the wall of the carriage is thus prevented since the water is directed from the wall of the collection trough into the collection trough.

In the trough-like inner floor, according to another development, drains for fluids are provided in order to guide the fluids out of the carriage. Such drains are also in particular provided in the collection troughs. In this instance, both the drains in the collection troughs and those in the trough-like inner floor may be arranged in alignment with each other, or they are constructed so as to complement each other in such a manner that the fluid in the drain of the collection trough is guided through a drain of the trough-like inner floor from an inner space of the rail vehicle. The fluids may be collected below the trough-like inner floor or be discharged into the track bed.

According to another development of the carriage according to the invention, the inner floor is provided in the region of a passage with a water-tight anti-slip layer whose edges are horizontally joined to the surrounding components by means of a water-tight joining compound. The passage acts in particular as a floor. The anti-slip layer may in this instance be laid as a coating on the trough-like inner floor, or it was applied as a coating. In an embodiment, the joining compound, in particular in the horizontal direction, is applied with a width of at least 6 mm.

If there are gaps which are vertical or which are inclined relative to the planar surface of the trough-like inner floor, in particular between fitted modules, which gaps adjoin the passage, according to another embodiment they are joined with a water-tight joining compound which is at least 30 mm deep. The passage thus also forms a water-tight trough. The joining compound may in this instance be identical to the joining compound for sealing the water-tight anti-slip layer. It is also possible to consider doors in this instance as the fitted modules.

According to an embodiment of the invention, the carriage consequently has three trough-like collection systems which are independent of each other for leakage water. Water is often discharged from the water-carrying fitted modules and is collected by the collection troughs and guided out of the carriage. However, water is also occasionally spilt in the passage, and accumulates there and can be readily disposed of. If water or other fluids are discharged at unforeseen locations, for example, owing to a defect, for example, on a defective water or waste water line, this is collected at the latest by the trough-like inner floor and discharged. Transfer of fluid into the carcass is consequently prevented in a reliable manner.

The invention permits numerous embodiments. It is explained in greater detail with reference to the following figures, in which an embodiment is illustrated in each case. Elements which are the same in the figures are given the same reference numerals.

FIG. 1 is a perspective view of an inner floor of a rail vehicle according to the invention,

FIG. 2 is a partial cross section of an inner floor according to the invention,

FIG. 3 is a perspective view of a vertical gap which is sealed according to the invention,

FIG. 4 is a perspective view of a water-carrying fitted module with a collection trough according to the invention,

FIG. 5 is a cross section of a foot plate,

FIG. 6 shows another foot plate with an angular strip having two members at right angles inside the foot plate,

FIG. 7 is a cross section through a passage from the trough-like inner floor portion to a trolley cupboard,

FIG. 8 is a cross section through a wall of the rail vehicle, which wall delimits the trough-like inner floor portion.

FIG. 1 shows an inner floor of a rail vehicle according to the invention. An otherwise planar inner floor 1 has a trough-like inner floor portion 2. Water-carrying galley modules are in particular arranged on the trough-like inner floor portion 2, whereby the trough-like inner floor portion 2 is arranged below the water-carrying galley modules. The water-carrying galley modules are not shown here for reasons of clarity. In this instance, the trough-like inner floor portion 2 is formed by a collection trough 3 which is arranged on the planar inner floor of the carriage. This is produced, for example, from high-grade steel and comprises at least one drain 4. The drain 4 accordingly guides fluids from the collection trough 3 through the inner floor 1, out of the vehicle. Also not shown in greater detail is how the collection trough 3 extends behind a galley module as far as a height of at least 600 mm above the inner floor 1. However, this is illustrated in FIG. 4.

Furthermore, the planar inner floor 1 may have at the edges thereof a circumferential profile, whereby it is also constructed in a trough-like manner, which in this instance, in this embodiment, is not the case. In this instance, the inner floor 1 comprises floor plates 6 of plywood, which are provided with tongues and grooves and are connected to each other by means of the engagement of a tongue and groove. In addition, it has securing holes 8 by means of which it is connected, for example, screwed to a carcass. In this instance, it is coated in a water-tight manner and the abutting edges of the groove and tongue and the securing holes 8 are sealed with a water-tight joining compound 7, for example, Sikaflex. Edges and apertures of the floor plates may further be sealed with paint throughout.

In FIG. 2, a trough-like inner floor portion is drawn as a partial cross-section. A water-tight anti-slip layer 5 is applied as a floor covering to a floor plate 6, whose edges 9 are joined with a water-tight joining compound 7 with respect to an adjacent galley module 10. In the passage region, gaps, not only with respect to the galley modules themselves, but also to cupboards or other non-water-carrying modules, are joined. Foot plates in a transition region to a passenger space are also sealed with joining compound. In this instance, the water-tight joining compound 7 is applied at a width of approximately 6 mm and a depth of approximately 6 mm. FIG. 3 shows vertical gaps, which are joined with the water-tight joining compound 7 at a depth of approximately 30 mm. The gap which is joined in this instance is a gap between a fitted cupboard 11 and a door frame 12. Therefore, the otherwise planar inner floor 1 has in the passage region at the edges thereof in the passage region a circumferential profile, whereby it is constructed in a trough-like manner.

The collection trough 3 of FIG. 4 extends as far as a location behind the water-carrying fitted module, in this instance a washing module 10 which is placed backward onto a non-illustrated side wall of the rail vehicle.

A foot plate 13 according to the invention from FIG. 5 connects two substantially planar floor plates 6 which are coated in a water-tight manner. Such a foot plate 13 is in particular arranged in the transition region from a galley to a passenger space. It comprises, for example, a metal or a plastics material. If it is screwed from the upper side, the screw is covered with a water-tight joining compound. Alternatively, the foot plate 13 is, for example, adhesively bonded. In this instance, the foot plate 13 is arranged so as to overlap the floor plates 6. Therefore, these extend below the foot plate 13. In this instance, the foot plate 13 has at both sides a recess which is constructed so as to complement the foot plates 6 and which is provided in this instance with a right angle. Together with a substrate which is arranged below the floor plates 6, these recesses each form a groove. The floor plates 6 act as springs by being introduced into this groove. The intermediate spaces between the foot plate 13 and the floor plates 6 are filled with a water-tight joining compound 7. Joining compound 7 which oozes out of the intermediate spaces during production is smoothed.

Alternatively, the foot plate 13 comprises an angular strip 14, in this instance an angular strip 14 which is equal-sided at right angles and which is then connected, in particular in a water-tight manner, to the otherwise substantially planar inner floor portion which in this instance is formed by the floor plates 6, for example, in a materially engaging manner by means of an adhesive connection. A water-tight anti-slip layer 5 is applied to the floor plate 6 and overlaps a first member of the angular strip 14. This affords the advantage that another component, in this instance the foot plate 13, which surrounds the angular strip 14 and consequently conceals it from passengers, no longer has to be sealed with water-tight joining compound, but instead can be simply screwed on. A free region 17 between the foot plate 13 and the anti-slip layer 5 serves to compensate for tolerances.

The same principle is reproduced in FIG. 7, in which the transition to a trolley cupboard is shown in cross section. A first member 15 of the angular strip 14 is arranged parallel with and on the floor plate 6, and a second member 16 of the angular strip 14 delimits the otherwise substantially planar inner floor portion of the trough-like inner floor portion. The first member 15 of the angular strip 14 is arranged between a water-tight anti-slip layer 5 and a floor plate 6 and connected at least to the water-tight anti-slip layer 5 in a water-tight manner, for example, adhesively bonded. The angular strip 14 is concealed by means of a foot plate 13. However, in contrast to the foot plate 13 of FIG. 7, no persons will walk over this foot plate 13, but instead trolleys will be pushed or pulled. A space 17 for tolerance compensation is also provided.

In FIG. 8, there is also arranged on a floor plate 6 an angular strip 14 which itself is coated with a water-tight anti-slip layer 5. The angular strip 14 has two members 15 and 16 which are located at an angle of 90° with respect to each other. The angular strip 14 forms in this instance a profile which surrounds the otherwise substantially planar inner floor portion of the trough-like inner floor portion, together with a wall 18. As a result of the wall 18, the galley is, for example, delimited from a passage or a passenger space. In addition, the wall 18 has a U-shaped profile 19 which, in the same manner as the angular strips 14 from the embodiments of FIGS. 6 and 7, is inserted in a wet state, that is to say, is connected to the floor plate 6 by means of adhesive or a sealing or joining compound, such as, for example, Sikaflex. In addition, the U-shaped profile 19, in the same manner as the angular strips 14 from the embodiments of FIGS. 6 and 7, can be screwed to the floor plate 6. The U-shaped profile 19 serves additionally to fix the wall 18.
